Wow, and I thought my son was diagnosed young at the age of 6. Poor baby. I've heard Boston Children hospital is a good place. You have a lot of options up these with all the hospitals. Your daughter's symptoms sound a lot like my son's initial work up. But I knew in my gut it was UC. Unfortunately, I was correct. All I can say, is trust yourself. Another place to go that I know is very good is Dartmouth Hitchcock in NH. My sister in law has Crohns and uses someone up there, but I know her guy is not a peds doc. it's a good hospital and med school. I in NJ so I'm fortunate to have a medical school close to home. It make a big difference. Please let us know how you make out with your baby, she is way to young to be going through all this.
